Hi, I'm new.
I am going to Costa Teguise with my boyfriend in February for 2 weeks, and it's actually my first trip abroad without my parents

. There are a few questions I'd like to ask the more experienced travellers here.
1) What is the current exchange rate British Pound to Euro in lanzarote? The rate at Thomas Cook is $1.33 and if I order it in advance from
http://www.crowncurrencyexchange.com I can get $1.37.
Should I change my money in UK? Or wait until I get to lanzarote?
2) I'm going self catering at Los Zocos apartments. We are on a budget for food because we would like to go on excursions and try diving. Should we go all inclusive? Or can we go AI once every 3 days or something?
Thanks in advance!
